Thisinvention .concernsa novel and userful lfluid: or liquid sprayhead,the primary objeet of which is to diffuseor distribute water or other liquid inla wide and extensive inanneinsoithat a very'larg'e amount of liquidsurface inaybelpresented to the action of the air. The invention is especially apipli'eable to cooling-towers and also wont-of- :door cool-ing:ponds wherewith it is desirable to tlistrihute or diifuse the water 1 and bring it into contact with asilarge an amountof air as possible during the cooling process. In so i doing it is important i that the slot in th e nozzle through whichsthe :wateris ejected should have a substantialsizesoithat it will inot become easilyclogged with-debris or other foreign matter. "lln carrying the invention into practical effect, therefore, ll coinbinewith a split spray nozzle iaplurahty of' splitting devices located in proximity to eaeh otherand -=re1noved *toa distance from thejwater emitting slot so that the main stream 'of water issuing from the nozzle will be subdivided into a pluralityofi sheets or Vapor areas, whieh-willgaiford a large aqueous-surfacefto be aetedupon by the circulating currents of air; and further, the invention may be said to comprlse numerous details and peculiarities in the construction,

arrangement, and combination of the Vari- 40 ous parts, substantially as will *behereinafter described and claimed.

The spray head is composed essentially of a pipe 1 which may terminate inany desired manner, but usuallyhas a flattened or widened end 2 having therein a long fiat orifice or slot 3, whose walls are parallel to each other, as indicatedin Figs. 3 and 4, so that the stream of water passing through the pipe 1 froinlany source with which said jplpe may be connected, and striking the flattened end 2 will emerge through thelflat slot 3 in ,asheet of water having a. substantial Iwidtlr and other proportions.

. The slot 3, is a fairly wide one, so that it will notbeco1ne;easilyclogged with foreign matter, such as the debris whichcommonly accumulates in a cooling tower, for it unnst be recognized that in cooling towers and the like where my present inventionmanifestly inay ha e a peculiar value, that theiaction ofthelwater should be free and its flownot easily obstructedor interfered with by the presence of foreign matter. i

Faipportedon the flat slotted nozzle 2 in :any, convenient manner, or mounted many suitable way with reference to said nozzle 2, is a plurality of splitters consisting of apluralityof yolres attaehedby means of tense to the slotted nozzle 2, or cast integral with the pipe for otherwise formed and arranged iii-order thancertaln portions of; saidsyokes which have sharpened edges may belocatedlopposite to the 1 slot 3 in the patlrof the issuingwstreain of water, the locationof said sharp edges beingiat a distance from thevslot 2. In ithe examplelof :the invention shown in Figs. .1, 2, 8, ands,

-l haveindicated two yokes 11-, 4, eachhav-- .ing a knife edge 4: oppositelto the slot 3, and a third intermediate,yolre 5 having a knife edge 5 also opposite to theslot 3. Hence, it will be seen that theedges P ofthe yokes l and the edge 5 of the yoke 5 are im- -mediately opposite to the outlet slot Eland reinoved. to a "distance therefrom, so that they will. be struck by the sheet ofwater issuing from the slot 3, and will consequently divide said sheet of water into a plurality of thin sheets which will bear a certain relation in thelr size to the sizeof theslot in the flatnozzle 2. Further, it

will be seen that the center splitter has its edge 5 nearer to the slot 3 than are the companion knife edges 4% of the splitters 4:, the

" 1 position of the knife edge 5 being also located centrally opposite to slot 3. Thespace between the splitters 4 and '5 will also bear a definite ratio to the size of theslot 3 in the nozzle 2. 'Hence, it will be understood thatthe knife edge 5 cleaves the volume of water issuing frointhe slot 3 into two parts, orso splits it that half is diverted to one side of the splitter 5 and half to the other side Each of these halves of the volume of water whiehissues from the .slot 3 when thus diverted to the sides of thesplitter 5 will strike the knife edges 4* which, as I have said, are located farther away from the slot 3tha-n is the knife edge v 5 and each of said half volumes will be split 7 .9

in *twa'in so that half or one-quarter of the original volume issuingfrom the slot 3 will be diverted to one side 0f each splitter-"4:

Y and half to the other side, so that in this way a plurality'ofvapor zones or areas of substantial 'size are created, and'thus the diffusion of the water'is very large, and a great amount of water surface is created andbrought into contact with the currents ofair which are circulating or flowing past or'around the spray head. 7

Although in the specific example of'the invention which I have just been describing I have referred to the splitters 4 and 5 5 as independent members bolted or otherwisesupportedupon the pipe1,yet it is evident thatthey may all be made integral with each otherand then formed with slots between the-several'knife edges, as there "main slot 3 are'disposed'in aproper manner sult will be the same, if so be that splitting edges properly'located with reference to the in relation thereto at a distance therefrom and; that proper channels are ofi'ered between the knife edges to enable 'the subdivided volume'of water to distribute itself in expanding sheets for the purpose in view.

. Also, it will be evident that the knife edges "4:? and 5 may be differently located in refi erence to the slot 3 from what have shown parting from the invention, inasmuch as the them in Fig. 30f the drawing without dequestion of position andrelative arrangebeing d1- so'that'the outflowing water insteadof. strikat different distances from the center of the y issuing steam, and thus said stream will be cut into three equal parts, two of which will be diverted sidewise on the outer surfaces of the splitter 7 while the central portion will be a single third of the water which will enter and pass through the intermediate slot 8 between the two splitters 7, 7, but a result similar to that attained by the mechanism in Figs. 1, 2, and 3 will be achieved by the devices of Fig. 4: in substantially the same way with fully equal advantages,

which differ only in respect of the size and quantity of the volume of water which. is being handled. Further, while in this modification of Fig. 4: the pair of yokes 7 is shown, it will be evident that they might be made integral with a central slot, which will enable a pair of sharp cutting edges to be furnished of the sions;

r The splitters may obviously be multiplied so as to increase the subdivision and enlarge the water surface. The triangularity ofthe propershape and dimenmay be of greater or less length and bevel,

if'only' a' sufiieiently sharp edge in eachcase is furnished in the path of the issuing stream ciently. Further, it must be'kept in mind at all times that the primary stream of water coming through the slot 3 of the nozzle 2 from the pipe 1 must be of some substantial size, for the slot mustnot be small enough to be interferedwith by debris and other substances that would choke it up and destroy its utility, such substantial stream being essential "in cooling towersand other apparatus where tact with the air. Therefore, I desire, it clearly'understood that many changes in the precise construction and arrangement of the various parts may be made without exceeding the scope of my invention, and in all of such cases it will be evident that the cutting edges must be located in the path of the issuing stream and at a short distance from the slot in the nozzle. It willbe seen that when the cuttingedges are at different dis- I claim as new and tances from the slot any debriswill not be caught by the cutters but will be easily thrown off. I

Having thus described my invention, what terse Patent, is,:

1. The combination with a spraying nozzle having a wide flat end formed with an elongated slot therein through which a sheet of water emerges, said slot being of a substantial width to prevent clogging with debris, of a plurality of parallel cutters arranged in the path of the issuing stream at a distance therefrom and lying in the same gendesire to secure by Let "splitters may obviously vary in respect to the size of the angles and the knife edges of water to subdivide it quickly and efiithe water must be brought into intimate'coneral' direction as the elongated slot and 7 longer than the same, the middle one of said cutters being nearer to the flat slot than the others and situated centrally with reference to said slot so that debris and foreign matter will not be caught by the cutters but will be thrown off therefrom.

2. The combination with a spraying nozzle having a wide flat end formed with an elongated slot through which a sheet of water emerges, said slot being of substantial width to prevent clogging with debris, of a plurality of parallel cutters arranged in the path of the issuing stream at a distance therefrom and lying in the same general direction as the slot, one or more of the cutters being located nearer to the slot than the other to prevent debris from being caught by the cutters, said cutters having the func- 15 In testimony whereof I hereunto afiix my 20 signature.
